The mural appeared ahead of the referendum on whether the UK should remain in the European Union, which will take place on 23 June.

The verse referenced in the mural says: "And I heard another voice from the heaven, saying, Come out of her, my people, that ye not be partakers of her sins, and that ye receive not of her plagues."

Prof Drew Gibson, from Union Theological College in Belfast, told the BBC: "This verse is about the oppression of the poor by the strong. It's about those who search for luxury and want to leave God out of the equation.

"It is interesting in the context of our coming election and the Brexit debate where everybody is saying it's all about the economy, it's all about the economy, it's all about the economy.

"This verse says 'no, it's not actually all about the economy'.

"There's morality at the heart of it, there's spirituality there as well."
